A two-country model of oligopoly in general equilibrium is used to show how changes in market structure accompany the process of trade and capital market liberalisation. The model predicts that bilateral mergers in which low-cost firms buy out higher-cost foreign rivals are profitable under...

In this chapter we present a selective analytic survey of some of the main results of trade under oligopoly. We concentrate on three topics: oligopoly as an independent determinant of trade, as illustrated by the reciprocal-markets model of Brander (1981); oligopoly as an independent rationale...

This paper endogenises the extent of intra-sectoral competition in a multi-sectoral model of oligopoly in general equilibrium. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand behaviour,...

The current debate on the likely impact of completion of the market in the European Community focuses crucially on the nature of the market structure. It has been suggested that 1992 will move an industry from a segmented-markets equilibrium to one in which the national markets are fully...

This paper discusses the place of oligopoly in international trade theory, and argues that it is unsatisfactory to ignore firms altogether, as in perfectly competitive models, or to view large firms as more productive clones of small ones, as in monopolistically competitive models. Doing either...

I argue that increased foreign competition can affect technical choice and skill differentials even when actual imports do not rise significantly. I present a model of General Oligopolistic Equilibrium (‘GOLE’) in which a reduction in import barriers (whether technological or policy-imposed)...

I review briefly the empirical evidence in the trade and wages debate, which overwhelmingly rejects the Heckscher-Ohlin explanation for recent increases in OECD skill premia. I then argue that the same evidence is also difficult to reconcile in general equilibrium with the view that exogenous...

We depart from the trade and wages literature and its emphasis on North-South trade, examining North-North trade and linkages between trade-based integration and relative wages in an Etiher-type division of labor model. Using this model we identify a formal relationship between international...

This paper highlights analytical reasons why we believe trade and technology are linked to wage movements in general, and how we should organize our examination of the recent episode of wage and employment erosion in the OECD countries. We start with a graphic tour through the mechanics of...

This paper compares two policies: trade cost reduction and firm relocation cost reduction using a three-country version of a heterogeneous-firms economic geography model, where the three countries have different market (population) size. We show how the effects of the two policies differ, in...
